Thai Port were in complete control of the match just before the break with goals from Ekkachai on 20 minutes and Jacob Aikhionbare on 43. The idea should have been to keep it tight until the interval but Port gave BEC Tero a lifeline on the verge of half-time when Chris Brandon struck from inside the 6 yard box after an initial decent parry from Ulrich Munze.
Thai Port coach, Sasom, now had the decision of whether to add to the lead or shut up shop. After 10 minutes of the second half, Sasom raised a few eyebrows and pulled off two attacking midfielders for defensive midfielders.
It seemed a bit early to be closing out the game with 35 minutes left, but the decision was justified when substitute Worwut added a third in the 72nd minute.
The Fire Dragons did pull one back in injury time through Ekele Udojoh, although it was too little too late.
The result means that Thai Port are only 2 points behind BEC Tero now. The early season promise shown by BEC has long since disappeared and they need something to kick start their season. Thai Port will be glad to be in the comfort zone of mid-table after hovering above the relegation area for the early part of the season.
